The plant immune system
A detailed understanding of plant immune function will underpin crop improvement for food, fibre and biofuels production and provide extraordinary insights into molecular recognition, cell biology and evolution across biological kingdoms. Expand
Plant pathogens and integrated defence responses to infection
The current knowledge of recognition-dependent disease resistance in plants is reviewed, and a few crucial concepts are included to compare and contrast plant innate immunity with that more commonly associated with animals. Expand
Reactive oxygen species produced by NADPH oxidase regulate plant cell growth
It is shown here that RHD2 is an NADPH oxidase, a protein that transfers electrons from NADPH to an electron acceptor leading to the formation of reactive oxygen species (ROS) and that ROS accumulate in growing wild-type (WT) root hairs but their levels are markedly decreased in rhd2 mutants.

Genome-wide association study of 107 phenotypes in Arabidopsis thaliana inbred lines
Susanna Atwell*, Yu S. Huang*, Bjarni J. Vilhjálmsson*, Glenda Willems*, Matthew Horton, Yan Li, Dazhe Meng, Alexander Platt, Aaron M. Tarone, Tina T. Hu, Rong Jiang, N. Wayan Muliyati, Xu Zhang,Expand
A flagellin-induced complex of the receptor FLS2 and BAK1 initiates plant defence
BAK1 is shown to have a functional role in PRR-dependent signalling, which initiates innate immunity, and evidence is provided that FLS2 and BAK1 form a complex in vivo, in a specific ligand-dependent manner, within the first minutes of stimulation with flagellin. Expand
Bacterial disease resistance in Arabidopsis through flagellin perception
It is shown that treatment of plants with flg22, a peptide representing the elicitor-active epitope of flagellin, induces the expression of numerous defence-related genes and triggers resistance to pathogenic bacteria in wild-type plants, but not in plants carrying mutations in the flageLLin receptor gene FLS2.

Arabidopsis gp91phox homologues AtrbohD and AtrbohF are required for accumulation of reactive oxygen intermediates in the plant defense response
Paradoxically, although atrbohD mutation eliminated the majority of total ROI production, atrabohF mutation exhibited the strongest effect on cell death, which is observed after infection of mutant lines with P. parasitica. Expand
A Plant miRNA Contributes to Antibacterial Resistance by Repressing Auxin Signaling
It is shown that a flagellin-derived peptide induces a plant microRNA (miRNA) that negatively regulates messenger RNAs for the F-box auxin receptors TIR1, AFB2, and AFB3, implicating auxin in disease susceptibility and miRNA-mediated suppression of auxin signaling in resistance. Expand
Role of plant hormones in plant defence responses
Recent advances made in understanding the role of salicylic acid, jasmonates and ethylene in modulating plant defence responses against various diseases and pests are reviewed. Expand
Genome sequence and analysis of the Irish potato famine pathogen Phytophthora infestans
The sequence of the P. infestans genome is reported, which at ∼240 megabases (Mb) is by far the largest and most complex genome sequenced so far in the chromalveolates and probably plays a crucial part in the rapid adaptability of the pathogen to host plants and underpins its evolutionary potential.
